As Arctic summers warm, Earth's northern landscapes are changing. Using satellite images to track global tundra ecosystems over decades, a new study found the region has become greener, as warmer air and soil temperatures lead to increased plant growth.

Sustained greenhouse gas emissions could see global sea levels rise nearly 40 centimetres this century as ice sheets in Antarctica and Greenland continue to melt, a major international study concluded Thursday.
The gigantic ice caps contain enough frozen water to...
Deforestation in the Brazilian Amazon has increased abruptly in the past two years, after having been on a downward trajectory for more than a decade. With the country's president Jair Bolsonaro notoriously enthusiastic about expanding into the rainforest, new...
Economists frequently try to estimate the societal cost of releasing carbon dioxide into the atmosphere, but few of their projections go beyond the year 2100—far short of the millennia it takes for the climate changes from burning carbon to...
One way to make better predictions of global warming in the coming centuries is to look at climate change in the geological past.
In research published in Nature Communications, an international team of university experts from Germany, U.S. and UK—including the...
A University of Arizona-led team has nailed down the temperature of the last ice age—the Last Glacial Maximum of 20,000 years ago—to about 46 degrees Fahrenheit (7.8 C).
Their findings allow climate scientists to better understand the relationship between today's rising levels...
A new paper, co-authored by a University of Sussex scientist, has revealed major holes in an international treaty designed to help repair the ozone layer, putting human health at risk and increasing the speed of climate change.
Evidence amassed by...
Greenland lost a record amount of ice during an extra warm 2019, with the melt massive enough to cover California in more than four feet (1.25 meters) of water, a new study said.
After two years when summer ice melt...
Trees are one of humans' biggest allies in the fight against climate change, soaking up around 30% of the carbon we pump into the atmosphere by burning fossil fuel.
And over the past several decades, it has appeared that cold-climate...
Research published this week in Earth System Dynamics reports that the most sensitive climate models overestimate global warming during the last 50 years.Three scientists from the University of Exeter studied the output of complex climate models and compared them to temperature...
Northwestern University researchers have combined climate modeling with public health data to evaluate the impact of electric vehicles (EVs) on U.S. lives and the economy.
A new study found that if EVs replaced 25% of combustion-engine cars currently on the...
